This OSB is a good sheathing for roofs. Just make sure your joists are spaced properly and you cover the OSB properly with felt paper or appropriate underlayment and then your flashing and shingles. good luck with your project.
Not enough information to answer your question. Sheathing just the exterior of the walls, the interior or both? Do you need sheathing for the roof? How tall is your shed? if for the exterior is 4x8 the outer most dims? Lets assume you're sheathing the exterior fo the walls and t's 4'x8' for the outer most dims and the height is 8' for each wall. that means you'll need one sheet for each 4'Wx8'H wall and two for the 8'W x 8'H back wall. You'll then also need another two for the front wall, depending on cutouts for doors, windows, etc. No you're looking at roughly 6 sheets to do the outer side of the walls. if you need them for the roof then you'll need more depending on the dims of your roof. If the outer dims of the walls are even slightly over 4'W and 8'W, or taller than 8' high you'll need to compensate for the extra area. What about the floor area? Do you need some for the floor? To determine how many sheets you'll need for your project just measure and calculate the square feet needed and then divide by 32 (that's the sf of one sheet of this OSB) to get the number of sheet needed. If you get an odd number then round up (since you can't buy 8.3 sheets, if that's what your calculation comes out to be, it means you'll need 9 sheets, for example). Good luck with your project.
Probably not very well. Asphalt isn't as dense as concrete and the fasteners you use and may, over time, loosen up and move. You might look into an adhesive of some kind to glue your substraight down. Home Depot has many options in store and on line.
Yes it can. I used it for sub flooring but it can also be used for roof decking. I would give a word to the wise, T&G (tongue and groove) can be challenging to line up and may pose a danger on a roof. Be careful.
I would use it as a subflooring. I don't think a waterproofing coating would be sufficient for the wear and ear a balcony would endure. Weather would immediately exploit any wear points and degrade the OSB.
I never put one on a scale but to me they are pretty light. I can carry 2 at a time easily if the wind isn't blowing!
yes you sure can do that.
T&G are only on the length
I'm using liquid nail and don't anticipate any future problems with swelling from the glue.
I do not know. I checked the piece left over and did not see "exterior" written anywhere on it..
